Answer:
False
Step-by-step explanation:
Let's list all the odd numbers less than 15.
13, 11, 9, 7, 5, 3, 1
Prime numbers are numbers that can only be multiplied by 1 and themselves. But, we can see, that 9 can be multiplied by 3 and 3, making it a not-prime number (sorry I don't remember the exact name for that, I'm blanking out).
The number 9 makes that statement false.
Hope I helped! ouo.
